    The solution does not become more "clearish" when the reaction happens - the solution is clear both before and after the reaction. It does, however, become colourless.

      clear isn't the same thing as transparent...
      and yes they do become colorless, but clear isn't the same as transparent.
      clear is a way of saying its colorless like saying something is crystal clear instead of cloudy. Copper sulfate is transparent blue. its not clear blue.

    Great sketches of the glass! My teacher would've just drawn a rectangle without the top line

    I remember doing this experiment in my first year chem course a few years ago lol. Fun stuff!

      do it again. Zinc sulfate is great for electroplating iron metals before they rust.
      its not just a cool science experiment. it has very practical applications anyone can use at home.
      copper sulfate is great for copper plating too. having a jar of each you can copper then zinc plate for even better rust preventive measures.
      im using them on rusty motorcycle parts after i let them sit in vinegar to remove rust.

      Hearing copper sulphate made me remember a fact that copper sulphate is blue in colour. more you know!

    That was amazing thank you

    Isn't electonegativity the tendency to attract electrons in a covalent bond. because Zn and Cu are not covalently bonded, the reduction potential should be used instead?

    Sal instead of just drawing the reaction all the time can you please make a chemistry vid of you doing the experiment outside on khan academy

    But can ordinary CU (not CU2+) oxidise zinc?

    Copper is slightly more electronegative than zinc

    I don't want to doubt the great khan, but I think you meant that zinc would be more electronegative than copper...

      +TboneIsRogue Doesn't electronegativity increase from down to up, and left to right?

    • @TboneIsRogue

      Sakib Wasif Generally, yes. There are exceptions like zinc where you get a sudden drop in electronegativity because zinc's d-orbital (valence shell) is completely full (i.e., harder to add an electron).

    but where was the experiment?

    whycu and zn doest not make bond....
